MEANS FOR FORIVIING FLOATS FROIVI LOGS OIF WOOD.

Specification of Letters Patent.

Patented May 15, 1906.

To all whom it may concern,.-

Be it known that I, HEINRICH BUTEN- SCHN, a subject of the German Emperor, and a resident of Hohenwestedt, Germany, have invented an Improved Means for Forming Floats from Logs of Wood, of which the following is a specification.

This invention relates to a means for formingfloats or log-rafts, and comprises channelirons and connecting-bolts whereby a certain number of logs of wood are formed into a float, so as to enable them to be floated down rivers.

In the annexed drawings, given by way of example, Figure 1 shows a cross-section of a log-raft on the line A B of Fig. 2. Fig. 2 is a plan view of a portion of a float or raft. Fig. 3 shows the union of a connecting-bolt and channel-irons.

The logs constituting a raft are held between series of oppositely-placed channelirons a, the number whereof varies according to the length of the raft. To the channelirons are connected thebolts c, which are pivoted at their lower ends on the transverse bolts b, which pass through the lower channel-irons. Catches or lugs d are arranged on one side of the pivoted end of the bolts and bear against the irons a, when the bolts move in the direction of such lugs. In order to increase the rigidity of the connections, the lugs d are placed sometimes at the right and sometimes at the left of the connecting-bolts. The logs are placed in the frames or compartywith the members of the lower course and passing through the members of the upper course and having nuts Aapplied to their upper ends.

2. Means for forming rafts of logs, consisting of a plurality of channel-irons arranged in an upper course and a lower course, bolts connecting the members of said courses together, said boltslpivotally connected with the members of the lower course, means for limiting the pivotal action of said bolts in one direction, and means for locking said bolts to the members of the upper course.

In testimony whereof I have hereunto set my hand in presence of two witnesses.

HEINRICH BUTENSCHN.
